Austenitic Grain-Size of Steel Metallurgy

As fine-grained materials have better room temperature strength,ductility,toughness and other properties,thus,many heat treatments are carried out to obtain fine-grain structures.As most of the heat treatment performed on steels alter the grain-size,it is essential to control the grain-size of steel to achieve better properties.As-rolled conditionThe rolling process also homogenizes the microstructure and refines the grain size.After being rolled,the plate is cooled in static air.The term as-rolled condition stems from the fact that the product is not heat-treated.This rolling method is used for materials that are subsequently heat-treated by the customer (heat-treatable steels). results for this questionWhat is fine grain practice?What is fine grain practice?Fine Grain Practice.This is in connection with Carbon steel plates.Some specification calls for fine grain steel and specify that the grain size is to be checked as per E 112.2) Is it possible to take a fine grain (Fine grain Melting Practice material) to be subsequently heat treated and get a corse grain (By annealing).Fine Grain Practice - Metal and Metallurgy engineering - Eng-Tips
